Join us for another guest post, this time from Claudia Fugazza of the Family Dog Project in Budapest. Claudia's here to discuss her recent publication in Applied Animal Behaviour Science on the efficiency of new methods in dog training.

Hi Mia and Julie,

Formal training methods used until now rely mainly on the well-known rules of individual associative learning. These methods work perfectly well for a very wide range of animals — pigeons, rats, dogs and even crabs — and human and non-human animals can learn by ‘click and treat,’ as noted in the popular training book by Karen Pryor.




However, recent research has found substantial evidence that dogs could be predisposed to acquire information socially via the ‘Do as I do’ method. Do as I Do is a relatively new training method for people to use, based on dogs’ social cognitive skills, particularly on their imitative ability. 



With this training technique, dogs learn new behaviors by observing and copying their handler. The dog is a copycat. This method relies on social learning, and it was recently introduced in the applied field of dog training. 




As this method has started spreading in the dog training world, we felt that its efficiency and efficacy needed scientific testing. We were also wanting to know whether this method would be more or less efficient than other current training methods in training for particular behaviors.

We expected that dogs would more easily copy object-related actions from a human demonstrator so we tested dogs’ efficiency in this kind of tasks. To do this, I travelled across Italy and the UK with my video-cameras as well as a heavy Ikea cabinet filled with objects (you can imagine the weird looks I got from security personal at checkpoints!). I used these objects to test dogs learning to open or close drawers and lockers, pick up items from it etc. Since training methods can be affected by the skills of the trainer, only experienced dog-owners pairs who achieved a certificate either for the ‘Do as I do’ method or for shaping / clicker training were included in the study. Each pair was tested using ‘his’ method for teaching three different object-related actions in three testing sessions.


We expected that the ‘Do as I do’ method would prove more efficient for teaching complex tasks, compared to the shaping method that relies on individual learning. This expectation comes from what we know in humans: we tend to rely more on social learning when required to learn something difficult.

Our research found that the ‘Do as I do’ method proved more efficient for teaching dogs complex tasks, like close a drawer, open a locker and pick up an item that was inside (i.e., the time needed by the owner to obtain the first correct performance of the predetermined action was shorter with the ‘Do as I do’ method compared to shaping). We did not find a significant difference in the efficiency of the methods for teaching dogs simple tasks like knocking over a bottle or ringing a bell.

Now that we know a bit more on how to efficiently teach complex object-related actions, we are curious to know what happens when we want to teach different kind of complex actions, like body movements. We also want to know whether introducing social learning in dog training could have an effect on learning cues for trained action. 

We are aware that learning rates can be influenced by many factors, and we acknowledge that this study is just a very first step towards a more scientific approach to training paradigms. However we believe that this kind of information can be very important for the practitioners working in the applied field of dog training. We hope that the readers will not misinterpret the results and will not extend them to different actions and situations that were not tested.

Furthermore we would like to emphasize that, despite being efficient for training some kinds of actions, the ‘Do as I do’ method does not replace the methods based on individual learning (for example think of how many actions are not imitable at all if the demonstrator is a human and the learner is a dog!). Instead ‘Do as I do’ is a useful (and fun!) addition to existing training paradigms. Experienced dog trainers may find effective ways to mix the different training techniques in order to obtain the best results with each dog.

Hi Mia!

So many books. Written about dogs. Most I see at the airport, memoirs of someone’s ‘very special relationship’ with a 'very special' dog, another about dogs ‘racing in the rain,’ (seems like it would be a pretty short book, or would make a better YouTube video), and some even feature a dog as a private eye (many are fans of this one, see Patricia McConnell’s review).

Sometimes while sitting in the living room I joke with my boyfriend, “Pass me the dog book." Maybe I find this WAY more funny than he does, but like you, I am surrounded by dog books! Right in front of me is The Domestic Dog (Serpell, ed), and to my right I can see Genetics and the Social Behavior of the Dog (Scott and Fuller). Beneath that is What the Dog Knows: The Science and Wonder of Working Dogs (Warren).


Now we’ll all be surrounded by one more dog book, Domestic Dog Cognition and Behavior The Scientific Study of Canis familiaris! This one I am particularly biased towards because it is edited by Alexandra Horowitz, and I co-authored one of the chapters with her. As an edited volume, Horowitz -- and her way with words and dogs (she authored Inside of a Dog) -- stands behind the text, but each chapter has its own focus and tone. The book is in three parts:
  • Part I covers the perceptual abilities of dogs and the effect of interbreeding
  • Part II includes observational and experimental results from studies of social cognition – such as learning and social referencing – and physical cognition in canids
  • Part III summarizes the work in the field to date, reviewing various conceptual and methodological approaches, and testing anthropomorphisms with regard to dogs
  • The final chapter discusses the practical application of behavioral and cognitive results to promote animal welfare


Here’s a look at a few chapters in detail: 

Canine Olfaction: Scent, Sign, and Situation
Think you know canine olfaction? Think again! This chapter by Gadbois and Reeve discusses topics like “zoosemiotics" and “canine olfactory psychoethology.” Yeah! (and yes, the words “peemail” and “Nosebook” appear in this chapter). More about Gadbois and his work here.

Dog Breeds and Their Behavior
This chapter by James Serpell and Deborah Duffy is probably of interest to many (and it is already listed on the book website as “popular content”). They note that while there are some “breed-associated temperament traits, such as, German shorthaired pointers deliberately selected for nervousness/fearfulness,” it’s generally more complex than that on an individual basis. More about Duffy here, and Serpell here (and Serpell edited the 1995 book, The Domestic Dog).

Measuring the Behaviour of Dogs: An Ethological Approach
What do ‘dog cognition’ studies actually look like? This chapter, by Claudia Fugazza and Ádam Miklósi, takes readers on a behind-the-scenes tour of research in practice with topics like single-subject studies (dogs like Chase, Rico, Betsy etc.), comparative studies, and the presence or absence of owners during cognitive tests. For a further look into dog cognition studies, check out http://www.cmdbase.org. It’s a “web-based system that facilitates the exchange of videos among students of animal behavior.” More about Fugazza here, and Miklósi and the Family Dog Project here.

Looking at Dogs: Moving from Anthropocentrism to Canid Umwelt  
This chapter begins, "As a companion to humans, the domestic dog is naturally interpreted from a human-centered (anthropocentric) perspective." In this chapter, Alexandra Horowitz and I cover recent research into attributions to dogs, particularly the "guilty look" and inequity aversion, as well as factors that can impact peoples' interpretation of "human" in dog. We also investigate anthropocentric and canid-centric elements of our own and others’ research. Horowitz Dog Cognition Lab here

The remaining chapters cover:
  • Marc Bekoff: The Significance of Ethological Studies: Playing and Peeing
  • Ludwig Huber, Friederike Range & Zsófia Virányi: Dog Imitation and Its Possible Origins (Clever Dog Lab)
  • Emanuela Prato-Previde & Sarah Marshall-Pescini: Social Looking in the Domestic Dog (website)
  • Alejandra Rossi, Daniel Smedema, Francisco J. Parada & Colin Allen: Visual Attention in Dogs and the Evolution of Non-Verbal Communication
  • Sylvain Fiset, Pierre Nadeau-Marchand & Nathaniel Hall: Cognitive Development in Gray Wolves: Development of Object Permanence and Sensorimotor Intelligence with Respect to Domestic Dogs (Canine Cognition Lab)
    For those working with shelter or working dogs, the final chapter by Rooney and Bradshaw is incredibly useful. Scratch that. Anyone who cares about dogs should understand how animal welfare science can be applied to canines.

    What can I say? Books about canine behavior, biology and cognition are great.

    VetPen, for use with Vetsulin (in USA) and Caninsulin (outside USA)
    The U.S. Food and Drug Administration (FDA) has approved the first insulin injection pen (VetPen, Merck Animal Health) for diabetic cats and dogs, the agency announced today, March 19, 2014 (1).

    2 Sizes of VetPens
    The VetPen may now be used to administer Vetsulin insulin cartridges, also made by Merck Animal Health. The refillable VetPen automatically measures the prescribed insulin dose and provides the owners of diabetic dogs and cats with an additional option for insulin delivery.

    There are two sizes of refillable VetPens. One (tan cap) dispenses insulin doses from 1-16 units per dose in full unit increments. The other (blue cap) dispenses 0.5-8 unit doses in full or half unit increments. Both pens use 2.7 ml insulin cartridges which hold a total of 108 units (IU) of U-40 Vetsulin (or Caninsulin).

    Vetsulin is an FDA-approved insulin for use in dogs and cats (2). This insulin is identical to Caninsulin, the brand name of the insulin sold in Europe (3).

    Merck said the VetPen is easier to dose and administer and is more accurate than traditional delivery systems, such as syringes and vials (4). “For years, insulin pens have made managing diabetes more convenient for human diabetics,” the company said. “Merck Animal Health has now brought the same technology to veterinary medicine.”

    An informational website (2) provides tools for both veterinarians and pet owners to make managing pet diabetes easier. More online information about the VetPen can also be found on the Caninsulin website (5); the Pet Diabetes website has an informational brochure that can be downloaded (6).

    I am writing you regarding my 11-year old male Weimaraner, Duke. He has always been in good health but over this past week he has had 2 ”accidents” where he has urinated in the bed. He has also been drinking a lot more water than usual and urinating more too.

    I  took him to the vet because I had a feeling he might be diabetic. My veterinarian confirmed that it was indeed diabetes mellitus and started him on 10 units of NPH, once after breakfast and once after dinner.  He has improved since starting the insulin, but remains quite thirsty and continues to urinate excessively.

    Now I know that this will not give very good control alone because NPH is only a long-acting insulin. I am a Type 1 diabetic, diagnosed when I was 12 years old, so I have quite a bit of experience dealing with this disease. I want my poor puppy to be as controlled as possible so he does not feel like I do when my sugars are out of control— lethargic, nausea, headaches, unquenchable thirst, urinating all the time, and just plain crappy! Not to mention the stress this puts on the on the rest of the body.

    If dogs are anything like people, I believe that Duke needs an insulin mixture that will bring his blood glucose down to normal and keep it leveled out. I have been giving him the rapid-acting insulin analog Humalog (insulin lispro) along with the NPH and that seems to be working really well, with marked improvement in his thirst and urination.  The only problem is that he needs 4-6 injections of Humalog each day. I was hoping you have had experience with something that would give him the same control as Humalog but with less injections daily.

    In the past, I have used short-acting Regular insulin (before Humalog was invented) but I do not remember how the dosing went. I do have much better control with the Humalog but I am also on an insulin pump, so NPH insulin is no longer necessary.

    Any help you can give to allow my dog Duke better control long term without so many injections would be greatly appreciated.

    My Response:

    In dogs, veterinarians commonly start with an intermediate-acting insulin (NPH or Vetsulin) twice a day (1,2). In some dogs, I find it necessary to add a short-acting insulin to the longer-acting insulin preparation, but many dogs can achieve adequate glucose control without giving more than 2 injections per day.

    Insulin of choice for canine diabetics
    In my opinion, the insulin of choice for most dogs is Vetsulin (porcine insulin zinc suspension; Merck Animal Health) (3). The main advantage of Vetsulin (known as Caninsulin outside the USA (4), is that it is actually composed of both short- and long-acting insulin components (see Figure below, showing the duel peaks of activity) (5,6). So giving Vetsulin is like administrating NPH together with a second, short-acting insulin preparation, like you are doing now.  However, Vetsulin works better than NPH for most dogs because it has a longer duration of action than NPH.

    Timing of meals and insulin injection
    The short-acting amorphous fraction of the Vetsulin, which composes 35% of the insulin activity, acts like regular insulin or Humulog, mainly to control the rise in blood glucose after each meal (6).  To help prevent severe rises in glucose after meals, however, it is also important to give the insulin before meals, instead of after the food is ingested, as you are doing now. This protocol will allow the short-acting insulin to be absorbed into the blood stream and ready to act to lower the blood sugar as soon as the food is absorbed from the gastrointestinal tract (7).

    The only time I don't do this insulin-feeding protocol is in dogs that don't always eat their meal well; but even in those dogs, I never wait long after the meal is finished to give the insulin. Instead, I always give the insulin injection as soon as possible, once the dog has eaten a sufficient amount of food.

    Hi Julie,

    Right off the bat I need to say YES YES YES! 

    Your last post about aggression and what we can learn from and about it WITHOUT the need to experience it was spot on. 

    Are you THIS attached to your dog? (source)
    You’re also right that my head is filled with glorious meta-analysis results right now, as well as perceptions and other measures (#allthemeasures!) as I start preparing my abstracts for submission to be part of the Canine Science Forum.

    One of the small but quirky things I’ve noticed in the results of the perceived welfare of dogs survey, is that people seem to think their own pet dog has a much higher level of welfare than everyone else’s pet dog. Why would we think we take better care of our own dogs than anyone else? Now, this could be to do with the self-selected convenience sample of people who took the online questionnaire. Perhaps the 2,146 people who were interested and motivated enough to take the time to do the survey really are the very top of the pile of all dog owners, but I found it interesting all the same.

    It got me thinking about our relationships with dogs (Ha! What’s new, right?!). I also happened to have a chat with Hal Herzog (while recording an upcoming episode of Human Animal Science) and, amongst many other things, we talked about how animals and pets aren’t universally beneficial for all people. Some people don’t even like their dogs. We know from extensive research into human psychology that our attitudes are major predictors of our behaviour. So are people who really love their animals more likely to take better care of them? (The answer is no, not always). Why is it that even people like us, who really find dogs fascinating and work with them daily, can feel more of a 'connection' with one individual dog, but not so much another?

    Definitely attached to dog (source)
    When faced with a question like this, how do we measure these differences scientifically? We can look at (usually self-reported by the human) measures, such as time per day spent in the company, or interacting/sharing activities with pet dogs. This is valuable, but does not necessarily indicate emotional closeness of a person to their dog.

    Lucky for me, plenty of psychologists, including earlier members of the Anthrozoology Research Group have tackled this and worked hard to create scales that measure the human-animal bond. The Monash Dog-Owner Relationship Scale, or MDORS as it’s more affectionately known is a great example. MDORS is a series of questions that form a psychometrically sound and validated scale. 

    This scale was developed with the assistance of over 1,000 participants and comprises 28 items (statements that you agree/disagree with on a 5 point likert-style scale) across three subscales: Dog–Owner Interaction (e.g. “How often do you play games with your dog”), Perceived Emotional Closeness (e.g. “I wish my dog and I never had to be apart”), and Perceived Costs (e.g. "It is annoying that I sometimes have to change my plans because of my dog"). A scale like this can be used not just to assess how attached people are to their pet dogs, but also to explore how these attachments might vary between dogs, and with different groups of people (e.g. from different countries, with different cultural, work experience or education backgrounds, etc.), making it a very powerful tool for researchers. 

    (excerpt from Dwyer et al, 2006)
    Used in conjunction with other questionnaires to investigate areas like grief at the loss of a pet, responsible pet ownership practices by owners, oxytocin levels in dogs, or human health benefits derived from pet ownership; attachment measures, like MDORS, can help us learn more about the importance of attachment to successful relationships for both human and dogs.

    How many dogs are you attached to? (Flickr)
    You might remember Tammie King's research, that used a modified version of the Ainsworth Strange Situation to see what dogs did when separated from their familiar person  and approached by a stranger (in her case, helping to measure the canine trait of amicability through their reaction toward the stranger). Tammie also asked owners to complete the MDORS and used the results in interpreting the canine behavioural data analysis for her PhD.

    So often in our research, it's important to measure both sides of the story, because we've learned the experience of the human, or even the human's perception of the dog's experience, just don't match up to the dogs' experience.

    I'm pleased to see you'll be tackling topics like these this weekend in San Francisco at the Canine Science Symposium event - yet another great line up of fantastic canine scientists sharing science for everyone:

    Meanwhile, I'm getting back to my research and pondering if attachment might relate to perceived welfare of dogs.

    Looking forward to your next update,

    Mia
